1 When autumn #comeS, the days #get shorter and the nights get longer.
2 We #use sunscreen when we #want to get tanned.
3 If you #had drunk too much coffee, you #may have felt tired.
4 The apple pie #WOULD taste better when you #added both sweet and sour apples.
5 When you #ARE feeling in danger, adrenaline #turns on the fight-or-flight response, which #enables you to struggle or to flee from the danger.
6 If you #put a raw egg into a hot spring, it #gets cooked in less than an hour.
7 When people allergic to shellfish #ARE eating shrimps, their skin soon #covers with an itchy rash.
